Parenchymal liver enhancement with bolus-triggered helical CT: preliminary clinical results

A software-driven device for bolus-triggered start of helical computed tomography (CT) was evaluated in liver studies of 30 patients with suspected metastatic liver disease. Compared with results in a control group of 30 patients who underwent conventional contrast material-enhanced helical CT, the study group had significantly higher and more constant parenchymal enhancement (P < .05, Mann-Whitney U test). This technique helps optimize findings at contrast-enhanced helical CT.
